I rarely say this, but not broken. Cruise ships have different boats for the crew and for the passengers. The passengers one will be self-sustaining, with food and medicine supplies for all the passengers and an automated distress beacon. The crew one will have full communication equipment and a powerful engine to get near enough to another ship to radio for help, and will only be big enough for the crew.

You should have been told the emergency procedure shown the location of your allocated lifeboat boarding area when you boarded the ship (by law); if you weren't, complain.
